Cinco DNSSEC Mayo

For many, the switch on May 5th to the new DNSSEC support in the root server pool is long overdue, for others the swich has people jumpy dreaming up reasons why this will "kill your internet". While Keith Mitchell, head of engineering at root server operator Internet Systems Consortium says "No-one is going to completely lose Internet service as a result of the signed root -- or indeed any DNSSEC deployment efforts -- and I certainly didn't say that it," he says of the Register story. "The worst that is going to happen is that a tiny minority of users behind mis-configured firewall or middleware boxes may experience some performance degradation when their clients have to attempt alternative paths for resolving names," says Mitchell.

As defined by "it was designed to protect the Internet from certain attacks, such as DNS cache poisoning [0]. It is a set of extensions to DNS, which provide: a) origin authentication of DNS data, b) data integrity, and c) authenticated denial of existence."

This is intended to protect people from far worse things (phishing, DNS poisoning, rewriting, etc) than having to resolve names through alternate servers. For an easier description wikipedia as always has us covered.

Happy Cinco DNSSEC Mayo!

Anti-virus Statistics - Motivations

In a study completed and published by Avira ( ) The results of the survey showed that for 34 percent (3,207 respondents) a long-established, trustworthy brand was key. Almost as many users, 33 percent (3,077 respondents), based their decision on the virus detection rates achieved in independent tests. Detection rates - lets call this effectiveness of the control - as this is the key metric used to measure effectiveness. This is a skewed metric as for the large majority of evaluations (ICSALabs, VB100, etc) use the "in-the-wild" or ITW list of viruses to perform the evaluations. There is no evaluation of these product's ability to respond or even detect newly released virus and malware. In all honesty really what we are dealing with here is preventative vulnerability management not virus detection and correction, and in my opinion there are four types of preventative protections required f

Local Classified Penny Auction Scam

While there are a lot of new posts regarding the new ways to exploit people using novel techniques and 0day exploits, there continues to be a rash of tried and true methods of coercion.  I want to just walk through a simple example and reflect on how effective these methods continue to be. Many people turn toward online classified sites to buy and sell items online.  This example starts with which even I've used on occasion to find used electronics and other items.  Doing a search on the site for a " Samsung Galaxy Note 2 " returns a posting from today with someone selling one for an unreasonably priced unit. $125 for a $500 phone?, but what if it's for real?  No harm in just asking some simple questions.  Email sent with some obvious questions regarding the condition and location. About an hour passes before I get a response from what appears to be a legit seller. Notice no answer to the questions I asked, but a friendly pointer at where th

OpenSolaris, ZFS, iSCSI and OSX - Creative Storage - Part II

In part I of this post, I looked at the simple steps required to setup a relatively simple storage solution using OpenSolaris, ZFS, iSCSI and OSX. This was about a month ago, and I've made some significant changes on how this is used for me. At the end of the last post I left off on the part dealing with configuration of the iSCSI initiator side of the solution. I stopped here because there were some issues related to the installation and use of the software. The iSCSI initiator that I was using was Studio Network Solutions GlobalSAN initiator (version which is used to allow for connections to their products. This software will also allow for connections to ANY iSCSI target! After the configuration of the iSCSI target on the ZFS pool, and installation of the client it was trivial to get the connection established with the storage pool, and it showed up in OSX as a raw disk which had not been formatted. I proceeded to format the disk as HFS+ and it then mounted as a lo
